Wow, what steve said Although looking at the pics, even with the front panel done the back/sides of the box are still open, no?
Have you put any thought into getting a better pump and trying for some higher voltages? Not that many people would appreciate the difference between a system good for 100mtorr or .01mtorr...

Yea, it's kind of a half-box, so I can still get at the pump valves and vacuum purge valve. It's nice to have it portable for demonstrations at my son's school and Geek Group events.
I'm always up for making bigger and better projects, I just don't ever seem to have enough money.

No matter it's just an odd plasma globe, it's still very cool.
How did you bend this what looks like 5mm aluminium? I never had a chance to work with such thickness, and I heard it's impossible to bend 90 degrees without breaking.

Ah, that's some great stuff. It's actually 1/4 inch plastic with aluminum bonded to each side. You cut a 45 degree "V" grove with a table saw through one side and the plastic, then bend it to the shape you want. It's strong and stiff, without being too heavy. My brother got me some scraps from a construction job he was working at a few years ago. I don't think you can purchase the stuff off-the-shelf retail. I don't even know who makes it, or what it's called. I made the box for my big variac out of it also.

Now you need to add some Deuterium gas and pump up the voltage/current so you can produce some neutrons..THEN that will be cool! (PLUS I would be knocked off my feet to see someone do that with a glass chamber!):-) Matt

That fusor looks great, Capper!
I've seen that aluminium/plastic sheet stuff made by Alcoa under the trade name Reynobond, in Europe at least. It seemed pretty expensive, though I bet it's cheaper than a pure aluminium sheet of the same thickness! (If aluminium is solidified electricity, like one guy said, then they saved money by making an electricity and oil sandwich...)
I'm not happy with aluminium just now, since I just cracked the MTB frame that I posted a pic of two pages ago :( I'm taking it to my local TIG welding expert for a verdict.
